I thought of one more thing, Abby. Have you ever had your IgG's tested? They are immunoglobulins.
For example, if someone has an IgA deficiency and are tested for celiac disease but they do indeed have the disease, their antibody tests may come back negative. Those tests are IgA tests.
MG antibodies are IgG tests. So if you have a deficiency of even one of the IgG's, you could look like you don't have antibodies when you might. These are the subgroups of IgG: IgG1, IgG2, IgG3 and IgG4. Dr. Vincent found that most acetylcholine antibodies are IgG1 and IgG3.
Just a thought.
